Abstract: METHOD OF JUSTIFICATION FOR A LINE        OF TEXT CONTAINING COMPLEX CHARACTERS     Abstract of the disclosure A word or text processing system is provided having a bidirectional printer with formatting capability.  A line of text is printed in one direction, and the printer is backspaced to form complex characters by adding overstrikes, such as underlining or accent marks.  The formatting unit includes a storage mechanism for storing encoded space images, including variable width spaces, in a first scan pass.  Space images overlapped by a backspace are deleted from the storage mechanism during the scan pass, and the number of spaces backspaced over is subtracted from the total count of expandable spaces available for justification. Upon detecting a space in the input data during the format pass, the system examines the space storage mechanism to determine if the image of the space is encoded therein.  A space is expanded for line justification only if the space is encoded in the space storage mechanism.

Abstract: Abstract Described herein is a process for enhancing the hydrophobicity of crystalline molecular sieves and also crystalline molecular sieve compositions which have enhanced hydrophobic character and modified catalytic properties.  The crystalline molecular sieves are contacted with a silicon tetrafluoride gas mixture at a temperature from about ambient to about 200°C to alter (1) the framework aluminum and silica content, (2) the surface characteristics, and (3) the acidic sites of the molecular sieves with resulting modification of both the adsorptive properties, i.e., enhanced hydrophobicity, and catalytic properties of the molecular sieves.  The crystalline molecular sieves can further undergo ion exchange to remove any aluminum fluoride cation species such as AlF++ and AlF2+.  The crystalline molecular sieve compositions of this invention are useful as selective hydrophobic adsorbents and catalysts.

Abstract: ABSTRACT OF THE DISCLOSURE        An   inspection   system   for   use   in   the fabrication of circuit boards of multiple, precisely registered  layers.   Each  layer  that  is  to  be precisely  registered  within  the  circuit  board  is formed  with  at  least  two  targets,  each  target corresponding  in  position  to  a  target  of another layer,  and  the  targets  of  each  layer  defining  a pattern that  is unique to that  layer.   Radiography techniques  allow a  viewing  of  the  registration  of each  target  of  a  layer  relative  to a  test  target pattern.  The test target pattern may be carried on a master template for the testing of individual layers for dimensional  stability prior  to stacking of  the layers  for  lamination.   Alternatively,  the multiple layers  may  be  stacked  in  their  desired  order,  in which case the test target pattern for the targets of one layer are formed by the targets of at least two other  layers.   Layer  registration  of  the  multiple layers  may be  viewed  prior  to  lamination,  with adjustment  or  replacement  of  any  mis-registered layer,  or  after  lamination  and  prior  to  further processing.  The targets may be formed in positions that define a pattern that is unique to a layer or in configuration that defines a pattern that is unique to a layer, or both.

Abstract: ABSTRACT OF THE DISCLOSURE         An  apparatus acts upon an extrudate rope to form individual elements of predetermined size and shape which are separated from one another by a predetermined space.   A die is used having a predetermined shape with indentations therein to press the extrudate rope against a support at predetermined locations.  A conveyor belt is used to carry the extrudate rope in one direction, and the die is supported such that during the pressing operation the die forward speed matches the extrudate rope forward speed.   A supporting table underlies the conveyor belt.  At least two shims are placed under the conveyor belt on either side of the path of the extrudate rope and underlying the path of the die so that portions of the extrudate rope which are pressed beneath the die are forced from under the die toward the indentations formed in the die so as to minimize waste of portions of the extrudate rope.  In one embodiment, a plurality opposing pairs of indentations are formed in both a leading edge and a trailing edge of the die.  Shims underlie those portions of the die lying between adjacent opposed pairs of indentations and lie in the direction of the motion of the extrudate rope.          Therefore, a plurality of extrudate ropes may be formed into pieces  simultaneously,  thereby  allowing  fast  and  economical separation of the extrudate ropes into pieces.   The shims between adjacent indentations cause portions of the extrudate rope which would otherwise underlie portions of the die between adjacent indentations to flow back toward the main body of extrudate rope thereby reducing waste.
